I love doing this activity with my students. In this file, you will find a January 2017 calendar with a math problem for each day. The neat thing about this activity is each day is the answer. For example, on Jan. 5th, the answer is 5. For Jan. 20th, the answer is 20. This calendar will have math that covers one and two step equations, one step inequalities, proportions, and order of operations. Students will have 31 problems to work out - They know they are correct if their answer matches the day!
Please follow me for the Feb. 2017, March 2017 and April 2017 calendars!
